What you're watching

The crew of Discovery Channel's popular science program, "Mythbusters," frequently gets ideas from fans. But they are about to take on a challenge from a particularly famous viewer: President Obama.

On the episode set to air Dec. 8, the president will appear in a walk-on and challenge Adam Savage and Jamie Hyneman to test the legend of Archimedes. Supposedly, the ancient Greek mathematician destroyed an invading Roman fleet by using only mirrors that reflected the sun's rays. Savage and Hyneman will devise an experiment to test the legend and report back the results.

President Obama will announce his "Mythbusters" participation during a White House event Monday celebrating math and science competition winners from schools around the country. Savage and Hyneman will be in attendance.
